I Have tested several popular anime titles known to be broadcasted in 720p format ex: naruto shippuden, Fairy Tail and selected 720p watched them
and have concluded that no anime or video on crunchyroll is streamed in HD.

Anime in HD 720p is much more clearer and sharper then what you are watching on here now.

Crunchyroll claims they stream anime videos in 720p. They are lieing.

ALL THERE SO CALLED "720P HD" is actually 640x480p upscaled to 1280x720p
